Abstract

Although the Internet can be used to provide high
connectivity between parties, it does not always provide
strong protection for private communications. Here we
describe a strong cryptographic solution to this problem
using one-time pads. One-time pads provide
cryptographically secure communication and can be
implemented using low-power computing devices such as
Pocket PC's, Palm-compatible devices, and even devices
for ubiquitous computing such as Javacard and iButton. A
method for the cryptographically secure transmission of
data between remote users is described, and prototype
implementations are presented for standard computational
platforms, handheld devices and Javacard enabled
devices.
